Transparent calculators for analytics thinking.

These tools make core decision concepts inspectable. They are educational utilities, not product predictions or financial advice, and they do not use private Seqube model parameters.

EXPECTED VALUE

Expected value calculator

Estimate the average outcome implied by a probability, upside and downside.

Probability of positive outcome (%)

Value if positive

Cost if negative

Expected value—

EV = p × gain − (1 − p) × loss

RETURN ON INVESTMENT

ROI calculator

Compare final value with the cost required to produce it.

Cost / invested value

Final / returned value

Return on investment—

ROI = (final value − cost) ÷ cost × 100

PROBABILITY CALIBRATION

Brier score calculator

Measure squared error between a probability forecast and a binary observed outcome. Lower is better.

Forecast probability (%)

Observed outcome

Brier score—

Brier = (forecast probability − outcome)²

NORMALISED PROBABILITY

Two-outcome margin normaliser

Convert two decimal prices into raw implied probabilities and normalise away their combined margin.

Outcome A decimal value

Outcome B decimal value

Normalised probability A / B—

normalised p = (1 / decimal value) ÷ sum of implied probabilities

These calculators are general analytical tools. They do not reproduce Seqube's proprietary model logic, do not constitute a prediction, and should not be treated as financial or wagering advice.
